Types of vegetable garden beds
Unframed bed In its simplest form, a garden bed is cut out of the turf, and the level of the garden soil is similar to that of the nearby ground, or slightly raised once amendments are added and soil is fluffed with a fork.
This simple form is perfectly fine in many cases and works especially well where the soil drains quickly. Basic raised bed A raised bed provides improved drainage and, best of all, the soil warms up faster in the spring. It is especially useful where the soil is heavy or poorly drained.
Making a raised bed can entail bringing in additional soil, but doesn’t have to. Copious amounts of compost and raking soil from the pathways onto the beds will achieve the same effect. Over time, the bed becomes higher with the continued addition of compost.
Raised beds don’t need sides to hold the soil in place. In fact, they’re easier to dig without sides. The soil might migrate a bit over the summer, but not a lot. A height of 15 to 20 cm is easily achieved without sideboards.
Steven says: I grow onions along the sloped edges of my raised beds as a way to make use of that space. Edged raised bed A more formal look can be achieved by edging your raised beds with brick, stone or wood. The beds can be as simple or as complicated as you wish.
Summary: Removing or covering turf allows you to jump right in with garden-making. There is no need to spend money at the hardware store for lumber or raised bed kits if you don’t want to.
